From E-pH As the figure shows, Youcui 811 Extraction You 2+ 、 With 2+ and Mn 2+ The capability is significantly superior to Calcium 2+ 、 Magnesium 2+ and Li + , its applications mainly fall into the following two categories:
- Lithium-ion Battery Recycling Process P204 The raffinate is a liquid containing a certain concentration. Magnesium 2+ /Li+/Ni 2+ /Co 2+ /Mn 2+ For mixed liquids, Youcui can be used. 811 Extract the mixed solution, and then You 2+ /Co 2+ /Mn 2+ Co-extraction to the organic phase, while Magnesium 2+ and Li + Remains in the raffinate and the wash aqueous phase; the stripping solution is of higher concentration. You 2+ /Co 2+ /Mn 2+ The mixed solution can be directly used for the synthesis of precursors for ternary lithium-ion battery cathode materials, thereby realizing a short-process lithium-battery recycling technology that delivers significant economic and environmental benefits.
- In laterite nickel ore, high-grade nickel matte, and MHP In the process of resource utilization, it is common to employ P507 or C272 Magnesium is removed by extraction, and the resulting magnesium-free solution typically contains magnesium. 20 – 40 g/L , containing nickel and cobalt 3 – 6 g/L . Adopting Youcui 811 Extracting nickel and cobalt from this high-magnesium solution is highly suitable, enabling the full utilization of nickel–cobalt resources and delivering significant economic and environmental benefits.
- Other about Ni/Mg Separation (high magnesium, low nickel), Co/Mg Separation, Mn/Mg Separation, Ni/Ca Separation (high calcium, low nickel), Co/Ca Separation and Mn/Ca Separation and other application scenarios.

UC272 is an acidic organophosphorus extractant; other members of this class include P204 and P507. P204 is widely used for the extraction of zinc, iron, manganese, and other elements, primarily in the early stages of smelting ternary precursor materials to remove impurities. P507 is mainly employed for the extraction and separation of nickel and cobalt as well as for the smelting of rare-earth elements; it is the most important acidic extractant and currently serves as the primary extractant in the industrial production of battery-grade cobalt sulfate and the enrichment and separation of light rare-earth elements. As an upgraded version of P507, UC272 boasts a nickel–cobalt separation factor of 7,000, significantly higher than that of P507 (280) and P204 (14). It is extensively used in the production of battery-grade nickel sulfate and battery-grade manganese sulfate and is a widely adopted extractant in the manufacturing of ternary battery materials. Moreover, compared with P204 and P507, UC272 requires a lower extraction acidity, is easier to back-extract, and exhibits excellent selectivity toward rare earths—particularly heavy rare earths. Consequently, its application has expanded from nickel–cobalt separation to the extraction and separation of rare earths, thereby driving rapid development in the rare-earth industry.
